Column Flotation Cells
For low feed rates, the improved recovery can be directly related to an increase in the flotation rate constant given by Equation [3]. As before, the higher recoveries result in the collection of additional middlings particles which tend to increase the product ash content. At high feed rates, the column becomes carrying-capacity-limited.

Recovering Gold through the Froth Flotation Process
Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.

Improving flotation energy efficiency by optimizing
The distribution of the energy dissipation rate within a flotation cell determines both the capture of ultrafine particles (high shear) and the detachment of coarse particles (low shear) (Jameson, 2013). Hence flotation recovery might be maximized by optimizing the proportion of the regions with high and low shear.
